Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cabinet used for televisions, radios, audio products, etc., and particularly to a cabinet with relatively large rounded corners.

. Conventionally, this type of cabinet has been formed with a thin wall portion 1 serving as the bottom of a substantially oval groove and a thick wall portion 2 continuing on both sides of the thin wall portion 1, as shown in FIGS. Cabinets are known that have rounded corners formed by a base material 3 covered with a synthetic resin exterior sheet 5 and a corner base material 4 covered by a thin portion 1 of the base material 3.

However, since the corner base material 4 of this cabinet has a circular cross-sectional structure, only the edges of the circumferential surface are used to obtain a relatively large roundness at the corner portion.

Therefore, the amount of material constituting the corner base material 4 is large, which increases the material cost, and it is large and tends to get in the way of storing items inside the cabinet, and there is a lower part that increases the weight of the cabinet.

Furthermore, since the corner base material 4 is a cylinder, it is impossible to position the arcuate end surfaces 2a of the thin wall portion 1 and the thick wall portion 2 of the base material 3 with respect to the corner base material 4, which prevents distortion when assembling the gear net. There are inconveniences such as the fact that this is likely to occur and it may not be possible to assemble it into a predetermined form.

The present invention was devised based on the above-mentioned circumstances, and its purpose is to provide a cabinet that can overcome the above-mentioned conventional problems.

An embodiment of the present invention will be described below with reference to FIGS. 3 to 6.

In the figure, reference numeral 11 indicates a base material having an exterior sheet 12 on its surface, which is molded from wood, particle board, plywood, hard synthetic resin, or a composite material thereof, and has a bottom of an approximately oval groove A. The thin walled portion 13 and other thin walled portions 13'
, and is formed with thick portions 14 or 15 that are continuous on both sides thereof.

The exterior sheet 12 is made of at least semi-rigid synthetic resin (
Preferably, the outer sheathing sheet 12a is made of vinyl chloride resin.

Although not necessarily necessary in the case of this embodiment, an inner interior sheet)-12b consisting of a sheet of paper impregnated with diarm phthalate resin, a phenol form aldehyde resin sheet, a fiber sheet, etc.
It is adhered to the inner surface of the outer sheath 1-12H to give the exterior sheath 12 its shape.

Note that the inner interior sheet) 12b further increases the strength of the exterior sheet 12, and also prevents expansion and contraction changes (occurring due to moisture absorption and drying) at the joint surface between the corner base material and the base material 11, which will be described later.
This is provided in order to further improve the attenuation of the influence of the surface of these base materials on the outer sheath H2a, and the conduction attenuation performance of heat generated during cutting to the shea H2a.

The thin part 13 of the base material 11 is obtained by cutting a part of the base material 11 from the back side,
This process also forms a substantially oval groove A.

Furthermore, protrusions 16 are provided at the edges of the thick portions 14 of the base material 11 facing the grooves A, respectively.

In this embodiment, the protrusions 16 are mounted separately from the base material 11 in order to reduce the thickness of the base material 11, but the above-mentioned cutting process is not limited to this. There is no problem even if it is cut out and installed at times.

Further, reference numeral 17 indicates a corner base material molded from hard styrene resin, wood, particle board, etc., which is covered with the thin portion 14 and forms a rounded corner portion together with the base material 11. ing.

This corner base material 17 has an arcuate contour line in contact with the thin portion 13 (indicated by a length X of the curve for convenience in FIG. 4) and a circular arc on the opposite side to this contour line X. The back side contour line forming the shape (indicated by the straight line length Y for convenience in FIG. 4), and a joining arcuate contour that connects these two contour lines X and Y and contacts the arcuate end surface 14a of the thick portion 14. It has a cross section surrounded by a line (in FIG. 4, for convenience, the length of the curve is shown instead as Z).

Furthermore, the corner base material 17 is provided with a stopper 18 at the boundary between its outlines Y and Z, and the protrusion 16 engages with this stopper 18.

Although this stopper 18 is integrated with the corner base member 17 in this embodiment, it may be attached separately.

In this embodiment, the arcuate contour line X is an arc of radius B, and the joining arcuate contour line Z is an arc of radius C, but these contours X and Z may be other curves and may be used in the present invention. The term arc should be interpreted to include the curves described above, and the backside contour line Y is not limited to a straight line, but may be a curved line or a combination of a straight line and a curved line.

Further, reference numeral 19 is another corner base material formed from the same material as the corner base material 17, which is covered with the thin portion 15.
Reference numeral 20 denotes an auxiliary base material with ventilation holes 20a formed from the same material as the base material 11, and these base materials 11, 20 and corner base materials 17 and 19 constitute a cylindrical cabinet shown in FIG. It is supposed to be done.

Furthermore, 21 is a corner material for connecting the auxiliary member 20 and the base material 11;
22 indicates a nail, and 23 indicates a wood screw.

In the above configuration, the joint surfaces of the base material 11 and the corner base materials 17 and 19 are bonded with an adhesive (not shown).

Therefore, when forming a relatively large rounded corner part with the corner base material 17 and the base material 11 in assembling the cabinet having the above configuration, the engagement between the stopper 18 and the protrusion 16 causes the corner base material to The joining position of the base material 11 to the base material 17 can be determined accurately.

Therefore, the work of forming the corner portions is facilitated, and a cabinet having a predetermined shape can be assembled while suppressing the occurrence of distortion.

Moreover, the corner base material 17 used for this rounded corner part is formed to have a cross section surrounded by the contour lines X, Y, and Z, and the cross section is not circular as in the conventional case. Although it is possible to form a section, the amount of constituent material is small and the shape is flat (it does not matter whether it is hollow or solid) and can be miniaturized.

Therefore, it not only has the cost advantage of reducing the material cost of the corner base material 17, but also helps reduce the weight of the cabinet, and due to the miniaturization, the corner base material 17 does not get in the way of the corners of storing items inside the cabinet. can be prevented from becoming

It goes without saying that the number and angle of the corner portions in the present invention are not limited to those in the above-mentioned embodiment, and in implementing the present invention, the base material and its thin and thick portions, It goes without saying that the specific structures, shapes, positions, materials, etc. of the exterior sheet, protrusions, corner base materials, their respective contour lines, stoppers, etc. are not limited to the one embodiment described above, and can be implemented in various configurations.

As explained above, the present invention provides a corner base material with an arcuate contour line to ensure a predetermined roundness, a back side contour line to make the corner base material flat rather than circular in cross section, and a corner base material for joining with the base material. Since it is formed with a cross section surrounded by an arcuate contour line for joining, the corner base material can be made smaller and lighter than before, reducing costs and weight, and improving the position of article storage. realizable.

Furthermore, a protrusion is provided on the base material whose surface is coated with an exterior sheet, and a stopper that engages with the protrusion is provided at the border between the back side contour line of the corner base material and the joining contour line. Therefore, the assembly work is facilitated, and the cabinet can be assembled into a predetermined shape without distortion.
